I received a gift from MasterCard few this year as a reward for their work. I have all the cards and we now have a few dollars on each card left. I would like on behalf of the remaining money for each card in a card so that you can use to make a purchase online. If I add the money from all the cards, I have enough for the article, which I had the eye to buy. Who knows how I do this? Thank you in advance for all suggestions.
